Paper Abstract

A general analysis of an inserted LPG in air-clad PCF for temperature and strain measurement is presented. The temperature and strain can be detected simultaneously by matrix inversion. The maximum temperature errors are 3oC and 0.8oC in the temperature ranges from 35oC to 50oC and 90oC to 120oC, respectively. The corresponding maximum strain errors are 250με and 135με in the strain range from 0 to 3000με respectively.
